C.E.VWARNER SWIETCH CONSTRUCTION Filed June 5, 1924 invention, it isobvious that it may be embodied in other forms covered and defined Y bythe appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the U; S. is

1. A circuit controller comprising a metal bushing having a tubularthreaded portion for extending through a panel and having also anannular flange, a nut screwed on the threaded tubular portion forholding it on the anel, a metal'plunger slidable back and forti in saidtubular portion, a contact carried by said metal plunger andelectrically connected therewith, a metal binding terminal membercomprising a terminal portion and an annular securing portion integralwith said terminal portion surrounding said tubular .portion and heldagainstsaid annular flange, anda combined binding terminal and contactmember comprising an annular metalsecuring portion'mounted on andsurrounding said tubular portion but insulated therefrom and comprisingalso a contact portion integral with said securing portion forcooperating with the contact carried by the plunger. n

2. A ycircuit controller comprising a metal bushing having a tubularthreaded portion for extending through a panel'and having also anannular flange, a nut screwed on the threaded tubular portion forholding it on the panel, a metal plunger slidable back and forth in`said tubular portion, a contact carried by said metal plunger andelectrically connected therewith, a metal binding terminal membercomprising the terminal portion and an annular securing portion integralwith said terminal portion surrounding said tubular portion and heldagainst said annular flange, and a combined binding terminal and contactmember comprising an annular metal securing portion mounted on andsurrounding said tubular portion but insulated therefrom and comprisingalso a contact portion integral with said securing portion forcooperating with the contact carried by the plunger, and means forinsulating the annularl portion of said combination member from saidannular bushing comprising a pair of insulating washers surrounding saidtubular portion, betweenwhich washers the annuvlar portion of saidcombination member is held, ksaid combination member having atlangeportion engaging the edge of one of said washers to position thecombination member.v

3. circuit controller comprising a Ametal bushing having a tubularportion for extending through a panel, a metal plunger slidable back andforth in said tubular portion, a contact carried by said metal plungerand electrically connected therewith, a metal binding terminal membercomprising the terminal portion and an annular securing portion integralwith said terminal portion surrounding said tubular portion and mountedthereon, and a combined binding tern'iinal and contact member comprisingan annular metal securing portion mounted on and surrounding saidtubular portion but; insulated therefrom and comprising also a contactintegral with said securing portion for cooperating with the switchcontact carried by the plunger.

4. A circuit controller connirising a metal bushing having a tubularportion for extending through a panel, a metal plunger slidable back andforth in said tubular portion, a contact carried by said metal plungerand electrically connected therewith, a metal binding terminal membercomprising the terminal portion and an annular securing portion integralwith said terminal portion surrounding said tubular portion and mountedthereon, and a Contact member mounted on said tubular portion butinsulated therefrom and cooperating with the contact carried by theplunger.

5. A circuit controller comprising a metal bushing having a tubularportion for extending through a panel, a metal plunger slidable back andforth in said tubular portion. a switch contact carried by said metalplunger and electrically connected therewith, and a contact membercomprising an annular metal securing portion mounted on and surroundingsaid tubular portion but insulated therefrom, and comprising a contactportion integral with said securing portion for cooperating with thecontact carried by the plunger.

6. A circuit controller comprising a metal bushing having a tubularportion for extending through a panel, a metal plunger slidable back andforth in said tubular portion. a switch contact carried by said metalplunger and electrically connected therewith` and a contact membercomprising an annular metal securing portion mounted on and surroundingsaid tubular portion but insulated therefrom, and comprising a contactportion integral with said securing portion for cooperating with thecontact carried bv the plunger, and an insulating washer mounted on andsurrounding said tubular portion, the annular portion of said contactmember having a flange engaging the edge of said insulating washer toposition it. l

In witness whereof, I have hereunto subscribed my name.
